FLUSHING APPARATUS FOR WATER-CLOSETS.

v "SPECIFICATION forming part'of Letters Patent No. 441,799, dated December 2, 1890.

Application filed August 19] 1890.

Serial No. 362,380. (No model.)

Be it known that I, JOHN KELLY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Water-Closet-Flushing Apparatus, of which the following is a specification.

' My invention is in the nature of an improvement upon the construction of apparatus set forth in Letters Patentof the United States No. 2 ,15,869, granted to me on the 26th day of November, 1889, for an apparatus designed for the same purpose as that forming the subject of the present application.

The operation of my aforesaid formerly patented device is, generally stated, to maintain supply of water in the bowl and traps between the latter and outlet-pipe by the normal air-bound condition of the traps, and to withdraw the air from the traps in flushing to permit free discharge from the bowl. This is effected through the media of an air-pipe leading from the higher of the two traps into the overhead water supply tank and terminating in a trap in the tank, a trapped flushing-pipe leading from the trap in the tankinto the bowl, and a valve-controlled pipe leading out of the tank from the air-pipe inside it, and therein provided with an aperture below the water-line. By opening the valvethe water contained inthe pipe it con trols, and which enters the pipe through its aperturereferredtoinsidethetank,discharges, drawing after it through the air-pipe the air from the waste-pipe trap, and also drawing from the trap in the tank the air it contains, thereby relieving the first-named trap of air, and thus removing obstruction to the evacuation of the bowl, and at the same time, by creating a partial vacuum in the tank-trap, which is in fact a siphon, drawing the water it enters the bowl. Sometimes it is not desirable to produce simultaneously the two operations of withdrawing the air contained in the trap between the waste-pipe and bowl and that contained in the tank-siphon, but rather to produce the last-namedoperation first, thereby causing the bowl to be supplied with the flushing water in a considerable quantity before the air-obstruction in the waste-pipe trap is removed.

The object of mypresent invention is to provide an improved construction of the flushing apparatus whereby the two operations referred to may be produced successively in the order stated.

In the accompanying drawings, Figure 1 is a view of my improved apparatus in elevation, partly sectional and broken; and Fig. 2, a broken sectional view showing an improved form of coupling desirable for connecting together the valve-pipe, tank-siphon shell, and flushing-pipe, details of the preferred form of my improved apparatus.

A is the bowl, communicating with the outlet-pipe B through the traps r and r.

0 is the overhead tank filled from the pipe q, leading into it from the source of supply, and which may be controlled for the usual purpose and in the usual manner by a suit able float-valve device D.

E is a cap of peculiar construction secured in rigid position at the upper side of the tank 0. The cap has a lateral threaded opening 1), and may be threaded around the opening of its under side, preferably around the inte rior thereof, as shown, and is further provided inside with a threaded central nipple 0, formed at the inner end of the opening 13. This construction of cap isvery readily formed by casting and easy to finish, and itaffords a convenient coupling for supporting the outer shell n, forming the short leg of atank-siphon F, and connecting with the latter the primingpipeG,bothhereinafterdescribed. Theouter shell n of the siphon F is coupled to the cap E, and thereby hangs inside the tank G, extending at its lower open end below the normal water-line of the tank.

H is the flushing-pipe extendingupward into the tank G and into the shell 71, but short of the top of the latter, and communicating at its lower end with the bowl A. The flushing-pipe should be provided with a trap r which may be, and preferably is, located, as indicated, near its lower end, or may be near its upper end, as illustrated in my said patent. The pipe G extends upward-into the overhead tank, and is therein connected, as by the narrower branch pipe m,witli the shell n, by coupling the pipe mwith the capE at its opening 19, and the pipe m is led some distance down into the pipe H, from the upper end of the latter, by an extension-pipe m, coupled to the nippleo in the cap. Thus the pipe G leads, to all intents and purposes, directly into the upper end of the flushing-pipe and forms with the latter and the shell n the tank-siphon F.

The lower end of the pipe G, provided withv a suitable shut-off valve Z, may lead to any desired point, even to the open air, though preferably into the bowl A, as represented, and inside the tank, below the water-line therein, the pipe G is provided with an inlet contains water, which enters it through the aperture 00.. On opening the valve Zthe discharge of the water from its pipe draws after it the air contained in the pipe H, as also that in the shell n, creating sufficient of a vacuum therein to raise water from the tank to the inlet end of the flushing-pipe H, through which it runs into the bowl until the water-line in the tank falls below the lower end of the shell 11. While flushing-water is thus being introduced into the bowl the coursing of the water through the shell n also draws air from the pipe I, thereby relieving the trap 1' and permitting the contents of the bowl to discharge freely into the outlet-pipe B. As soon as the water in the tank has fallen below the level of the aperture as in the branch pipe is it takes air through its aperture and thence introduces air again into the trap 0", thereby stopping discharge from the bowl, which then receives the desired after-fill supply (owing to the vent 00 being higher than the lower open end of the siphon F) by the continued running of water from the tank into the pipe H until the supplyin the tank falls below the lower end of the shell n. p i

The refilling. of the tank, as will be understood, is produced automaticallyin the usual manner under the control of the float-valve device D.

My stated object, which is thus effected, may also be accomplished by omitting entirely the pipe G (when, of course, there would be no opeuingp in the upper end of the siphon. F) and substituting forit the bent pipe G, (indicated by dotted lines,) normally submerged in the tank 0 and leading into the pipe H, being normally closed at its outer end, which extends upward to afford a valve-seat At the bend 'u, I extend from by a weighty valve Z, controlled through the medium of a chain 1*, or the like, extending to a point of ready access for the operator to permit the valve to be raised and lowered with reference to its seat.

Though the construction first described is preferred, it will be seen that by manipulating the chain Z to raise the valve Z, water from the tank will enter the pipe H through the pipe G and create the desired vacuum in the siphon F, thereby producing the same result as with the use of the pipe G and its extensionsm and m. If the valve l he raised only long enough to create a flow through the pipe H sufficient to form the desired vacuum in the siphon F, the operation will, obviously, continue until the siphon takes air at'its open base.
